Serving table



Patented Dec. 24, 1929 PATENT OFFICE GEORGE M. PATTERSON, OF KANSASCITY, KANSAS SERVING TABLE Application filed July 23, 1928.

My invention relates to improvements in serving tables. It relatesparticularly to the type of serving tables in which a table top memberis adapted for being lifted and revolved, so as to render articlescarried by the top member readily accessible to persons seated aroundthe table.

One of the objects of my invention is to provide novel means by whichthe revoluble top member may be lifted and revolubly supported. Afurther object of my invention is to provide a construction foreffecting such function, which is simple, cheap, durable, not likely toget out of order, which is easily and quickly operable, which will notbe liable to subject the articles carried by the top member to excessivejarring, and which has means for adjustment to compensate for wear orwarping of the parts.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings, which illustrate the preferred embodimentof my invention,

Fig. l is a side elevation, reduced, of a table provided with myimprovement, the revoluble top member being shown in the liftedposition.

Fig. 2 is an enlarged central vertical sectional view of the upperportion of my improved table, the revoluble top member being shown inthe lowered position.

Fig. 3 is a top view, reduced and partly broken away, of my improvedtable.

Fig. 4 is a section on the line 4l-A of Fig. 2, looking upwardly, andpartly broken away.

Fig. 5 is a section on the line 55 of Fig. 2, looking upwardly, andpartly broken away.

Fig. 6 is an outside elevation of the lever locking bar.

Fig. 7 is a perspective of one of the adjustable roller supportingbrackets.

Fig. 8 is a section on the line 8-8 of Fig. 5, parts being omitted.

Similar reference characters designate similar parts in the differentviews.

The table is provided with a support comprising a pedestal 1 on whichare mounted 5 two crossed horizontal truss members 2 to the Serial No.294,702.

ends of which is fastened a circular skirt member 3.

Respectively mounted on the end portions of the members 2 are blocks 4,which extend inwardly from and have their upper sides flush with theupper edge of the skirt member 3. On the blocks 4 and skirt member 3,and projecting outwardly from the latter, is a stat-ionary annular tabletop portion 5. Upon the members 2 at the intersection thereof andfastened thereto by bolts 6 is a tubular bearing member 7, which isprovided with a central vertical bore.

A flat circular horizontal revoluble top member 8 is revolubly fittedwithin the annular stationary top portion 5, and is adapted to rest, inits lowered position, on the upper sides of the blocks A which projectinwardly from the portion 5, with its top surface in the plane of thetop surface of the top portion 5, as shown in Fig. 2.

A central vertical spindle 9 is rotatably and vertically slidably fittedin the bearing memer 7, and has its upper end portion fitted in avertical hole in the lower end of a hub 10 of a member having radialarms 11.

The arms 11 are fastened to the under side of the revoluble top member8. A set screw 12 in the hub 10 bears against the spindle 9.

For lifting the top member 8 to the elevated position shown in Fig. l,and for supporting said member revolubly in said position, I provide thefollowing described mechanism.

A horizontal rin 18, concentric with the top member 8 and with the topportion 5, is revoluble around the axis of the top member 8 and has itsunder side resting on and supported by rollers ll, which arerespectively rotatable on horizontal radial pins 15, which arerespectively mounted in L shaped brackets 16, which respectively embracethe inner ends of the blocks 4, to which they are clamped by horizontalbolts 1? having nuts 18, Fig. 5, which bolts extend each through slots19 provided in the arms of the adjacent bracket. Each bracket 16 has anarm 20 which extends inwardly and then upwardly, the adjacent pin 15being mounted in alined holes 21 and 22 in the upwardly extending partof the arm 20 and the transverse portion of the Ushaped bracket. Byloosening the nuts 18, the brackets 16 may be vertically adjusted on theblocks 4, to compensate for wear or warping, and the nuts 18 thentightened to hold the brackets in their adjusted positions.

On the upper side of the ring 13 are mounted U shaped bearings 23, inthe arms of which are mounted horizontal pins 24 on which arerespectively mounted rollers 25 adapted to bear against the under sideof the top member 8, and to revolubly support the top member, when thering 13 with the rollers 25 thereon is lifted.

To lift the ring 13, when it is desired to lift the top member 8, theunder side of the ring 13 is provided with surfaces 26 which inclinedownwardly from the under side of the ring, and at their lower endsterminate in horizontal surfaces 27.

When the ring 13 is turned clock-wise, as viewed from above, theinclined surfaces 26 will respectively contact with the rollers 14 whichwill travel along the inclined surfaces, thereby lifting the ring 13,and, through the intermediacy of the bearings 23 and rollers 25, liftingthe table top members 8 to the position shown in Fig. l. The top maythen be rotated in either direction while resting on the rollers 25.

To turn the ring 13, it has fastened to it the inner end of a radialoperating lever 28, Figs. 3 and 5, said lever being extended through aninclined slot 29 provided in an arcuate bar .30, the ends of which arerespectively fastened to two adjacent blocks 4. The lever 28 is heldunder tension which tends to make it spring upwardly.

By swinging the lever 28 in the direction indicated by the arrows inFigs. 3 and 5, the ring 13, is revolved so that the inclined surfaces 26ride upwardly on the rollers 14, thus lifting the ring 13 and the lever28. hen the lever 28 reaches the upper end of the slot 29, the leverwill spring upwardly into an upwardly extending recess 31 at that end ofthe slot, thus holding the lever from moving from the uppermostposition.

At this time, the rollers 14 will have run onto the horizontal surfaces27.

To lower the top member 8, the lever 28 .is depressed from the recess 31and forced counter-clockwise, as viewed from above, thereby revolvingthe ring 13 so that the inclined surfaces 26 will pass off from therollers 14, and the ring 13 will reach the position shown in Fig. 2.

When the lever 28 has been swung to the extreme right end of the slot29, as viewed .in Fig. 6, the ring 13 will be in its lowermost position,and the top member 8 will again rest on the blocks 4, as in Fig. 2.

I do not limit my invention to the structure shown and described, asman-y modifications, within the scope ofthe appended claims, may be madewithout departing from the spirit of my invention.

l/Vhat I claim is 1. In a serving table, a support having a stationaryperipheral top portion, a central top member concentric with said topportion and vertically movable and revoluble on a vertical axis on saidsupport, means revoluble around said axis for lifting and supportingsaid top member, and means by which when said revoluble means isrevolved in the proper direction it will lift and revolubly support saidtop member.
